Components cannot be used in globally defined sub-flows or processor-chains

Details

  • User impact:
    Medium
  • Similar Issues:
    None

Description

Because components are singletons in spring this causes huge issues with the same component instance being used in multiple flows. Different FlowConstuct get injected from multiple flows in same object and all flows propagate lifecycle meaning if one flow is stopped the component is stopped for all others too.

This affects us via both <processor ref=""/> and <flow-ref name=""/>

relates to

Bug - A problem which impairs or prevents the functions of the product. MULE-5747 Sub-flows (and processors defined in them) don't get muleContext injected or lifecycle when used via flow-ref

  • Blocker - Blocks development and/or testing work, production could not run.
  • Closed - The issue is considered finished, the resolution is correct. Issues which are not closed can be reopened.

Silly question, can the components have a reference count and only pay attention to the propagated flow life cycle if the count is 1 or something like that?

Regardless of the implementation, this is confusing and no easy to explain to users.
